Improve logs from ansible, puppet, docker-puppet.py

* Debug ansible 'puppet apply' stderr joined stdout, split
  by lines.
* Do 'puppet apply' w/o colors, logdest syslog, and given a wanted
  modulepath instead of the module puppet, that can't support those
  options.
* Bind-mount syslog socket for docker-puppet.py to pass puppet logs
  to host OS syslog.
* Fix logging handlers for multiprocess workers in docker-puppet.py.
